This paper describes the use of layered conductive metal-organic framework (MOF) (nickel)3-(hexahydroxytriphenylene)2 [Ni3(HHTP)2] as a model system for understanding process self-assembly within this class materials. We confirm and quantify experimentally role oxidant in synthetic process. Monitoring deposition Ni3(HHTP)2 with situ infrared spectroscopy revealed that MOF formation is characterized by an initial induction period, followed linear growth respect to time. The presence identity oxidizing agents critical coordination-driven these materials impacts both length period observed rate growth. A large excess hydrogen peroxide results 2× increase (9.6 ± 6.8 × 10-4 vs 5.0 2.8 min-1) over standard reaction conditions, but leads large, irregularly shaped particles. Slower rates oxygen favor uniformly sized nanorods (98 38 25 6 nm). These quantitative insights into mechanism HHTP-based provide valuable information about fundamental aspects coordination polymerization are nanoscale crystal engineering structure-property relationships
